Title
(EN) METHOD FOR DETERMINING THE HEALTH STATUS OF THE HYDRAULIC CIRCUIT ARRANGEMENT
(FR) PROCÉDÉ DE DÉTERMINATION DE L'ÉTAT DE SANTÉ DE L'AGENCEMENT DE CIRCUIT HYDRAULIQUE
Abstract
(EN)
The invention relates to a method (25) of determining the health status of a hydraulic circuit arrangement comprising at least one hydraulic fluid working machine (2, 3). The health status is determined (29) using at least in part an actual temperature information (12) of the hydraulic circuit arrangement (1) that is compared to an expected temperature information (24) of the hydraulic circuit arrangement (1).
(FR)
L'invention concerne un procédé (25) de détermination de l'état de santé d'un agencement de circuit hydraulique comprenant au moins une machine de travail à fluide hydraulique (2, 3). L'état de santé est déterminé (29) à l'aide, au moins en partie, d'une information de température réelle (12) de l'agencement de circuit hydraulique (1) qui est comparée à une information de température attendue (24) de l'agencement de circuit hydraulique (1).
